Beetles in the family '''Chrysomelidae''' are commonly known as '''leaf beetles'''. This is a [[family (biology)|family]] of over 35,000 [[species]] in more than 2,500 [[Genus|genera]], one of the largest and most commonly-encountered of all beetle families.
Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5.<ref>{{cite web| title = Family Identification - Chrysomeloidea| publisher = University of Florida| url = http://eny3005.ifas.ufl.edu/lab1/Coleoptera/Chrysomelid.htm| accessdate = 2006-11-29}}</ref> They are distinguished with difficulty from [[long-horned beetle]]s (family [[Cerambycidae]]) by having the [[antenna (biology)|antennae]] NOT arising from frontal [[tubercle]]s. Adult and [[larva]]l leaf beetles feed on all sorts of plant tissue. Many are economically important pests of agriculture, for example the [[Colorado potato beetle]] (''Leptinotarsa decemlineata''), the [[asparagus beetle]] (''Crioceris asparagi''), the [[cereal leaf beetle]] (''Oulema melanopus''), and various [[flea beetle]]s.

One of the present subfamilies (Bruchinae) was, until recently, considered a separate family, while two former subfamilies are presently considered families ([[Orsodacnidae]] and [[Megalopodidae]]). Other commonly-recognized subfamilies have recently been grouped with other subfamilies, usually reducing them to tribal rank (e.g., the former [[Cassidinae]], [[Alticinae]], [[Chlamisinae]], and [[Clytrinae]]).
